[Abstract]:China's financial equipment market has been dominated by foreign manufacturers for a long time. Whether from the aspects of national financial information security, market development and the accumulation of core technology of financial equipment, it is imperative to study the core technology of banknote module. This paper presents a design method of electronic control system based on embedded control system. The STM32F103 enhanced microcontroller is used as the main control core in the banknote module control system. Each function unit of the banknote module is driven by the rich and powerful peripheral functions of STM32F103, and the whole collection of state information and the same allocation of resources are realized. According to the system requirements of each functional circuit, each functional module is designed and analyzed in detail. The working principle, selection parameters and driving circuit of the actuator, including electromagnet, stepping motor and DC motor, are described, and the working principle, driving circuit design and adaptive adjusting method of photoelectric sensor are introduced. The working principle, device selection and design circuit of communication unit, memory unit and display unit are given. The design method of PCB printed circuit board is given. For the electromagnetic compatibility problem of electronic control system, this paper gives the detailed design instructions from the two aspects of principle design and PCB design, and points out the problems and design methods that should be paid attention to in the circuit design.
